Working on a small embedded vector database lib (à la SQLite). Just finalized the file format, it works pretty great so far. Besides, it’s an excuse to learn rust and low level programming in general.

Personalized audio streams for language learners. Ideal for during driving or while doing chores.

https://listen.longyan.io/

At the intermediate level lots of learners struggle to find suitable content that matches their level and interests, more than a few learners turn to notebookLM podcasts to provide that, but that's a bit of a hassle to set up. So I built a platform that generates and manages infinite and shareable streams around your interests or specific vocabulary. It also provides live interactive transcripts (karaoke / teleprompter style) if you need it.

Core features work but still rough around the edges. Happy to help you out with any issues you encounter, languages to add, feature requests etc...

Evals for programming languages with formal verification. It's not clear how far we are from good coding performance in less popular languages in general, and formal verification has some quirks on top also.

My first coding project: built a PDF tool to save paper on expense reports

TL;DR: Expense reports were killing me (and trees). Built my first coding project – a PDF merger that fits multiple receipts per page. Planned to charge "one bike tire

worth" to recoup costs, but decided to make it free after learning so much from the community. [https://ahay.app/](https://ahay.app/)
